Extra Special Fare by The Tall'n

The Tall'n offered us a highly entertaining variation on the dreaded Sudoku
this week with an extremely impressive piece of grid construction. Gregson
has to confess to a bit of a senior moment though. Even after solving all
the clues and wondering why there were so many Ks in the grid, it still took
some time to spot that the six unchecked letters spelt SUDOKU and that the
central 9x9 square in the grid formed a Sudoku square - d'oh.

Classic Listener fare - which can't be said of the dishes on the menu, though.
Gregson will be passing on the ceratodus and, in hindsight, was surprised
not to find turkey on the menu.
